Our final game, Civilization 5, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression.

Remember when NVIDIA used to sweep AMD in Civ V? Times have certainly changed in the last year, that’s for sure. It only seems appropriate that we’re ending on what’s largely a tie. At 2560 the GTX 680 does have a 4% lead over the 7970, however the 7970 reclaims it’s lead at the last possible moment at 1920. At this point we’ve seen the full spectrum of results, from the GTX 680 losing badly to winning handily, and everything in between.

On a final note, it’s interesting to see that the GTX 680 really only manages to improve on the GTX 580’s performance at 2560. At 1920 the lead is only 8%, and at 1680 we’re just CPU limited. Haswell can’t get here soon enough.

This is just a rebadged mid-range card, the 680 has less memory bandwidth than GPU's brought out 4 years ago lol, what a ripp, I can see the big fat directors at Nvidia laughing at all the mugs that have gone out and bought one, thinking this is the real big boy to replace the 580... muppets. lol.Reply

Yes Nvidia clocked the ram over 6Ghz because their ram controller is so rockin'. In any case, the 7970 is now being overclocked, both are to 7000Ghz ram. Unfortunately the 7970 still winds up behind most of the time, even in 2650X1200 screen triple gaming.Reply

well i have been an ATI fanboi forever. So I am due a gfx upgrade which would of already happened if ATI priced their latest cards similar to previous generations. I will watch ATI prices over the next few weeks but it looks like i might be turning green soon. Reply

I agree with some of the sensible posts littered in here that Witcher 2 should be included as a comparison point, and most notably the ubersampling setup.i run 2x 580GTX SLI @1920 and i can't manage a minimum 60fps with that turned on. That would be a good test for current cards as it absoultely hammers them.

also, i don't know whether CeriseCogburn is right or wrong, and i don't care, but i'm just sick of seeing his name in the comment list. go outside and meet people, do something else. you are clearly spending way too much time on here...Reply

"At the end of the day NVIDIA already had a strong architecture in Fermi, so with Kepler they’ve gone and done the most logical thing to improve their performance: they’ve simply doubled Fermi."

Fermi Lite, you mean.

"Now how does the GTX 680 fare in load noise? The answer depends on what you want to compare it to. Compared to the GTX 580, the GTX 680 is practically tied – no better and no worse – which reflects NVIDIA’s continued use of a conservative cooling strategy that favors noise over temperatures."

No, the 680's cooling performance is inferior because it doesn't use a vapor chamber. Nvidia skimped on the cooling to save money, it seems.Reply
